When you execute your program with the "&" (background process) the shell spits out the process id but I can't seem to redirect that out put to a file. I don't want to use "pidof" after the fact either in case there is another process running with the same name.

If you are in a shell script the current process is $$. The previous
backgroung job is $!.
echo $$ > sh.pid
foo&
echo $! > foo.pid
